This is a quote from the article:
On sunny days, solar panels on the roof of Strizki’s detached garage generate more than enough electricity to power his home.
This is in New Jersey! Not the sunniest place in the world. I wonder why a place like Arizona, for instance, doesn’t have a vast majority of people using at least some solar power.
